About converting WGS 84 to SIRGAS 2000
Converting from WGS 84 (EPSG:4326) to SIRGAS 2000 (EPSG:4674) is the standard datum shift for any work in Latin America where SIRGAS 2000 is the official datum — Brazil, Argentina, Mexico, Peru, Chile and most of the rest of the continent.
SIRGAS 2000 is aligned with ITRF2000 at epoch 2000.4 on the GRS 80 ellipsoid; modern WGS 84 tracks ITRF and the difference at the South-American plate is a few centimetres at modern epochs. For most GIS work the conversion is effectively identity; for sub-decimetre survey work apply the published Helmert parameters against the appropriate realisation.
Why people convert EPSG:4326 to EPSG:4674
- Brazilian federal mapping (IBGE)
- Latin-American cross-border GIS data exchange
- GNSS surveying in South America
- Migrating legacy SAD69 / Córrego Alegre data through WGS 84

The EPSG dataset defines official transformation parameters for the reverse direction. See SIRGAS 2000 to WGS 84 — the parameters are invertible.
Convert EPSG:4326 to EPSG:4674 in code
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4326", "EPSG:4674", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
print(x, y)Target: EPSG:4674 — SIRGAS 2000

Frequently asked questions
- Are SIRGAS 2000 and WGS 84 interchangeable?
- At metre-level accuracy, yes. For sub-decimetre work specify a particular realisation and apply the appropriate Helmert transformation.
- How accurate is converting WGS 84 to SIRGAS 2000?
- Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift transformation in a desktop GIS.
- Does my data leave the browser when I use this converter?
- No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
